INCORPORATED, OF BOSTON, MASSACHUSETTS,

A CORPORATION OF NEW LA'STIN G APPARATUS.

Application filed November 24, 1915.

To all whom it may concern:

Be it known that I, CHARLES C. BLAKE, a citizen of the United States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented anew and useful Improvement in Lasting Apparatus, of which the following is a specification. I

The present invention relates to the manufacture of shoes, and more particularly to the manufacture of the welt Shoe devised by me in which the faces of the welt, upper and insole engaged by the outsole are in the same plane.

Heretofore to last this shoe the forepart of the upper was first updrawn, and was then held in its updrawn position against the edge face of the insole by a leather strap, called a. binder, which was wider than the thickness of the insole. This binder was then clamped to the shoe to hold the stretched upper firmly pressed against the edge face of the insole. I was able to employ a strap considerably wider than the thickness of the insole owing to the fact that the welt shoe devised by me, as first constructed, had no overhang around the forepart thereof. Now, however, my welt shoe is provided with an overhang so that the leather strap no longer forms a practical binder for binding the updrawn upper to the edge of the insole in the improved construction.

The object of the present invention is to produce a lasting apparatus by which the updrawn upper is bound to the edge face of the sole by a binder adaptable to the overhang of the Shoe.

To the accomplishment of this object, and such others as may hereinafter appear, the features of the present invention consist in certain combinations and arrangements of parts fully Set forth hereinafter, the advantages of which will be readily understood by those skilled in the art.

The various features of the present invention will be readily understood from an inspection of the accompanying drawings, in which,

Figure 1 is a plan of the partially lasted shoe;

Fig. 4 is a sectional front elevation on the line 1-4, Fig. 1.

In the illustrated embodiment of the invention the assembled shoe comprises an upper 1, having a lining pasted therein, and

a sole 2 secured to the bottom of a last 3. The last is provided with a raised bottom 4t which is separated from the upper-shaping surface of the last by a vertical shoulder 5. In order to impart an overhang to the forepart of the shoe the edge of the last bottom from a point adjacent the breast line on one side of the last to a point adjacent the breast line on the other side of the last is located within the projections of the upper-shaping surface of the last upon the plane of the last bottom (Fig. 1). The

forepart of the upper is first updrawn byany of the known means which are suitable or desirable and is then bound in its updrawn position against the edge face of the sole by a ropeor cable 6 of wire or other material. stantially equal to the thickness of the sole so that it may pass beneath the overhang on the last and tuck the upper snugly against the edge of the sole. The binder isthen The cable 6 has a diameter subclamped to the shoe to hold the stretched upper firmly pressed against the edge face of the sole.

The binder may be conveniently secured to the shoe by a clamp which is first positioned loosely about the binder and is then closed thereon. The clamp comprises a horizontal bar 7 which loosely supports depending posts 8 and 9 which are prevented from sliding off the ends of the bar 7 by pins 10. As shown by dotted lines in Fig. 3 (illustrating the contacting surfaces of the bar and posts) while the posts are free to slide upon the bar 7 when they occupy a position normal to the bar they may be cramped upon the bar by tilting them out of normal position. The posts are arranged upon opposite sides of the shoe and are each provided with a horn 11 (Figs. 1 and 3), which enters a hole 12 (Fig. 1), formed in the upper below the sole and engages the face of the sole, and with a concavely curved spring metal jaw 13 arranged to engage the binder. When the clamp has been engaged with the binder and sole in the manner described the post 8 is slid along the tipped thereon.

bar 7 to tighten the clamp on the binder. During the initial movement of the post 8 on the bar 7 the binder is firmly pressed against the post 9 until it becomes cramped on the bar 7 in the manner shown in Fig. 3. The the continued sliding movement ofv the post 8 presses the jaw 13 thereon firmly against the binder after which the upper part of the post 8 moves independently of the lower part thus cramping the post on the bar7. The clamp may be closed by pressure or by blows struck upon the post 8.

The heel seat of the shoe may then be lasted in the usual manner or the lasting of the heel seat of the shoe may be postponed until the shank of the shoe is lasted. Preferably the heel seat of the shoe is lasted before the shank thereof. After the heel seat is lasted the first operation consists in spreading the cement which holds the upper in its lasted position between the clamped upper and the edge face of the sole. It is not necessary in securing the upper to theedge face of the sole that the cement be spread over the entire edge face thereof. A small fillet of cement on the margin of the edge face of the sole is sufficient. The operative then spreads cement along the edge face on both sides of the sole from the juncture of the shank and heel seat to the point of meeting of the clamped upper at the forepart.

The shank of the shoe is lasted by closing the jaws 14 of a clamp (Fig. l) upon the upper. Each jaw is secured to the lower end of a post 15 which is arranged to slide upon a bar 16 between stop pins 17. The posts 15 slide upon the bar 16 when an ranged substantially normal to the bar and are clamped upon the bar when they are Each jaw 1a is formed of a convexly curved piece of metal which is shaped to fit the curvature of the sole at the shank thereof.

It will be clear to those skilled in this art, and with the general objects of the present invention in view, that changes may be made in the details of structure, the described and illustrated embodiment thereof being intended as an exploitation of its underlying essentials, the features whereof are definitely stated in their true scope in the claims herewith.

What is claimed as new, is

1. An apparatus for use in the lasting operation in the manufacture of shoes comprising a cable for binding the upper against the edge face of the sole and means for securing the cable to the shoe.

2. K11 apparatus for use in the lasting op eration in the manufacture of shoes comprising a cable having a diameter substantially equal to the thickness of the sole for binding the upper against the edge face of the sole and means for securing the cable to the shoe.

3. An apparatus for use in the lasting op eration in the manufacture of shoes, having, in combination, a cable for binding the upper against the edge face of the sole, and a clamp for clamping the cable in its binding position.

4:. An apparatus for use in the lasting operation in the manufacture of shoes, having, in combination, a cable for binding the upper against the edge face of the sole, a clamp for clamping the cable in its binding position, and a clamp for directly clamping the upper against the edge face of the sole at the shank portion thereof.
